Problem creating EFI system partition

Can you post a screenshot from diskmanger showing all details it sounds as if you have to many partitions as that what the error is

Hi, for anyone to consider this - why not post a screenshot of your partitions using a 3rd party partition manager such as Minitool Partition Wizard (not Disk Management)?

Have you reviewed this tutorial and comments following?
Convert MBR Disk to GPT Disk in Windows 10


And before attempting such a major change, please confirm you have created a full current 3rd party disk image so you can readily recover should it all fall apart.

I would also recommend as a matter of routine precaution that you check your disk before attempting this change.
(E.g. Hard Disk Sentinel)

Thanks.

I ran reagentc /info command on admin CMD.
Got the following info:

Looks like the Recovery Partition windows is using is partion 2.
Can one of the other two recovery partitions be deleted?
If so which one would be safe to delete.

Thank you for your reply.

Your screenshot is with Disk Management, not with a 3rd party partition manager.

You can delete the Recovery partition not in use.
I posted this yesterday in another thread. This should help you.

Recovery partition deletion - Ghacks

If you were to search tenforums you would find other examples of dealing with this.

@Raner

You already have 4 primary partitions on that disk.
The MBR2GPT command can't do the conversion, because it has to create another primary partition, which it can't do.

As mentioned above, you need to delete one of those Recovery partitions.
Then, MBR2GPT should work.

Thank you all for taking time to help me out.
According to what I'm seeing the following is the recovery partition windows is using:
Windows RE location: \\?\GLOBALROOT\device\harddisk3\partition2\Recovery\WindowsRE
So looks like the other two recovery partitions ( In my case Disk3 partition 3 and 4 ) can be deleted.

If you wish to cross-check when doing that with a 3rd party partition manager, and as I showed in the recent thread I mentioned with a screenshot, you can check the creation date of the content of the recovery partitions (rt click , Explore) and delete the oldest ones.
